The TAC SCM server is designed to generate highly variable market conditions in order to challenge the adaptability of competing agents. One problem area for TAC SCM research is the amount of time researchers must expend in order to glean significant results from test simulations. We propose changes to the server that address this issue, in the hope that more efficient testing will lead to more...

objective: active and passive smoking lead to the production of a number of oxidants and antioxidants with various adverse health effects compromising the immune system. tobacco use increases the production of free radicals as well. the purpose of this study was to determine the effects of passive smoking on total antioxidant capacity (tac) of serum and saliva in rats. methods: this experimenta...

Accurate amplitude and phase measurements of ultrashort optical waveforms are essential for their use in a wide range of scientific disciplines. Here we report the first demonstration of full-field optical reconstruction of ultrashort waveforms using a time-to-space converter, followed by a spatial recording of an interferogram. The algorithm-free technique is demonstrated by measuring ultrasho...

This paper presents an integrated receiver channel and an integrated time-to-digital (TDC) converter fabricated in a 0.35 mm SiGe BiCMOS and in 0.35 mm CMOS technologies, respectively, that give the required performance for a pulsed time-of-flight (TOF) laser radar to be used in a laser scanner in automotive applications. The receiver-TDC chip set is capable to measure the positions and widths ...

OBJECTIVES This study aimed to compare changes in coronary endothelial function, systemic endothelin-1 (ET-1) levels, and vascular remodeling in heart transplant recipients randomized to cyclosporin A (CyA) or tacrolimus (Tac) immunosuppression. BACKGROUND Functional endothelial abnormalities and intimal thickening are sensitive measures of early cardiac allograft vasculopathy (CAV). METHOD...

Various controlling schemes are used in dc-dc converters to control the output voltage, rise time, peak time and settling time of the response. In this paper, fuzzy logic and PID control technique are studied on Buck-Boost converter and the mentioned parameters are analyzed. The model is developed in MATLAB/Simulink.

A histogram-based method for quasi-static test of analog-to-digital converters has been proposed for standardization aims. The test exploits the use of small-amplitude triangular waves. Different signal offset values are used to fully stimulate the converter input range. The reduced amplitude and slope of the input triangular wave with respect to the converter range and slew rate, respectively,...

A receiver channel topology for a pulsed time-of-flight (TOF) laser rangefinder is presented. The designed compact IC receiver chip realized in 0.35 μm CMOS technology will include both a highperformance receiver channel and a time-to-digital converter (TDC). Its timing detection is based on the leading edge detection in the receiver channel. Amplitude-dependent timing error is compensated for ...
